From 27b75f56c92b82fe335ae8b5365095854086894f Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 8 Jul 2014 08:54:09 -0500 Subject: [PATCH] PowerPC: Cleanup powerpc memmove Now that MEMCPY_OK_FOR_FWD_MEMMOVE should be define on memcopy.h there is no need to specialized powerpc memmove implementation. This patch moves the define set to powerpc memcopy and cleanup its definition on powerpc code. --- ChangeLog | 10 ++++++++++ sysdeps/powerpc/memmove.c | 22 ---------------------- sysdeps/powerpc/powerpc32/power4/memcopy.h | 4 ++++ .../powerpc32/power4/multiarch/memmove-power7.c | 1 - .../powerpc32/power4/multiarch/memmove-ppc.c | 1 - .../powerpc/powerpc64/multiarch/memmove-ppc64.c | 2 +- 6 files changed, 15 insertions(+), 25 deletions(-) delete mode 100644 sysdeps/powerpc/memmove.c diff --git a/ChangeLog b/ChangeLog index 39fce07..1c7e41d 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,15 @@ 2014-07-08 Adhemerval Zanella + * sysdeps/powerpc/memmove.c: Remove file. + * sysdeps/powerpc/powerpc32/power4/memcopy.h + [MEMCPY_OK_FOR_FWD_MEMMOVE]: Define it to 1. + * sysdeps/powerpc/powerpc32/power4/multiarch/memmove-power7.c + [MEMCPY_OK_FOR_FWD_MEMMOVE]: Remove define. + * sysdeps/powerpc/powerpc32/power4/multiarch/memmove-ppc.c: + [MEMCPY_OK_FOR_FWD_MEMMOVE]: Likewise. + * sysdeps/powerpc/powerpc64/multiarch/memmove-ppc64.c: Include default + string memmove instead of removed powerpc one. + * sysdeps/powerpc/powerpc32/power4/multiarch/strcasecmp_l-power7.S: [weak_alias]: Fix compiler warning due trailing data. * sysdeps/powerpc/powerpc32/power4/multiarch/strcasecmp-power7.S: diff --git a/sysdeps/powerpc/memmove.c b/sysdeps/powerpc/memmove.c deleted file mode 100644 index 9c62ecb..0000000 --- a/sysdeps/powerpc/memmove.c +++ /dev/null @@ -1,22 +0,0 @@ -/* Copy memory to memory until the specified number of bytes - has been copied.
